Two 35-inch pumps from the figure (a) shown below are installed in parallel for the system of the figure (b) shown below. Neglect minor losses. For water at 20°C, take ρ = 1.94 slug/ft3 and μ = 2.09E−5 slug/ft⋅s. For cast iron, ε ≈ 0.00085 ft. 1) Estimate the flow rate and power required if both the pumps are running.  Q = ? in gal/min P = ? bhp   2) Estimate the flow rate and power required if one pump is shutoff and isolated. Q = ? in gal/min

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
